Nearly ten month old stopped eating and now waking in the night again....

My baby is ten months in a week. Two weeks ago she decided that she didn't want to be fed anymore - and will only eat if she can feed herself. Consequently, the amount of food that is going in has got to have reduced.
Her milk intake has increased over this period so that now she is having 10pz before bed and still waking in the night once or twice for another 5oz (although if it's after 4.30 this counts as her morning bottle).
I don't know what to do - it's like she has turned her day upside down and is now eating at night rather than day time.
Previous to this she was eating three nice sized meals a day, having three bottles (breakfast, 3pm and bed) and sleeping through till 8am!
Oh, we also used to give her hipp organic goodnight milk, but stopped a few months ago - well before all this started- cos we found she was throwing up a lot on it (the whole bottle!)
Help - I don't want to go back to having a baby that wakes in the night and is up at 5.30/6am for the day!! It's like having a newborn again!
Ps she is a chunky monkey (91st centile) so certainly not starving.

That's probably just a stage. My DS went through stages preferring more milk, going back onto more solids. Maybe in the warm weather she is more thirsty? Have you tried offering water at night instead of milk? Also re self feeding - if she persist, she will get much more efficient very soon. Sorry, no real advice, but in my experience such stages were resolving by themselves. Just keep offering a variety of food during the day. Their main nutrition still comes from milk, so don't worry about her getting not enough solids.
